Conventionally, two-pack type curable resin compositions each using a compound that has one or more (meth)acrylic groups in the molecule as described in Patent Documents 1 and 2 were known and various techniques have been conventionally known. In these techniques, the active effect is to accelerate curability and the active effect is common in two-pack type curable resin compositions other than those described in the patent literatures described below. For the purpose of improving curability, adding an amine compound and a sulfur compound is also a known technique.
